> Restrict failure and original relationship usage in NiFi python processors
> --------------------------------------------------------------------------
>
> Key: MINIFICPP-2439
> URL: https://issues.apache.org/jira/browse/MINIFICPP-2439
> Project: Apache NiFi MiNiFi C++
> Issue Type: Improvement
> Reporter: Gábor Gyimesi
> Assignee: Gábor Gyimesi
> Priority: Minor
> Time Spent: 10m
> Remaining Estimate: 0h
>
> In NiFi python processors the failure and original relationships are special
> and used in special ways.
> In case the result is "failure" the original flow file is transferred to the
> "failure" relationship with the added attributes in the
> FlowFileTransformResult, it cannot have any new content.
> The incoming flow file is forwarded to the "original" relationship
> automatically if the result is not "failure". This relationship cannot be
> used by the user as per the NiFi python developer documentation.
> These restrictions should be enforced in the NiFi Python API in MiNiFi C++ by
> raising an exception if any of the custom processors violate these
> restrictions.
